A nurse in an emergency department is reviewing a client's ECG reading.

Which of the following findings should the nurse identify as an indication that the client has first-degree heart block?

Prolonged PR intervals.

Nondiscernible P waves.

More P waves than QRS complexes.

No correlation between P and QRS waves.

Answer and Explanation

The Correct Answer is A

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.

Correct Answer is A

Explanation

Acupuncture is commonly used to treat a wide range of illnesses and ailments including pain management, control of nausea and vomiting, fatigue, hot flashes, xerostomia, neuropathy, anxiety, depression, and sleep disturbance in cancer patients.

However, I could not find any information that suggests mouth sores (B), headaches, or urticaria (D) are contraindications for acupuncture.

Lymphedema is a contraindication for acupuncture because it can increase the risk of infection in the affected area.

It is important for the nurse to identify this as a contraindication to receiving acupuncture therapy.

A. "What is meant by the saying, 'Don't beat around the bush?". B. "Can you tell me the state where you were born?". C. "Can you count backward from 100 in intervals of 7?". D. "What do you understand about your condition?".

Correct Answer is A

Explanation

Asking the client “What is meant by the saying, ‘Don’t beat around the bush?’” is a way to assess the client’s abstract thinking.
Abstract thinking involves understanding concepts and ideas that are not concrete or tangible, such as interpreting figurative language or proverbs.
Choice B is incorrect because it assesses the client’s memory rather than their abstract thinking.
Choice C is incorrect because it assesses the client’s attention and concentration rather than their abstract thinking.
Choice D is incorrect because it assesses the client’s insight and understanding of their condition rather than their abstract thinking.
